She remembered she began to feel very drunk, her memory became fuzzy and the next thing she recalled was waking up at her home naked in bed with Pohlman on top of her, the affidavit said. When she yelled at him to get off of her, he apologized and told her he "had to take care of her, that she needed help,'' she told investigators, the affidavit says.

A fourth woman who said she had dated Pohlman at one time, said she saw him again after they had broken up at a birthday party in December. He invited her and others to his car to ingest nitrous oxide from a tank in his car.

While seated in the back seat of his car, the woman said Pohlman suddenly injected her in the neck with a drug using an autoinjector – a spring-loaded medical syringe.

She was taken to OHSU Hospital, where she lay unconscious for up to eight hours, the affidavit said. She suffered an excessively rapid heartbeat, dilated pupils, rapid muscle contractions and mild hallucinations and blurred vision, according to a police review of her medical records.

The woman told police that Pohlman made his own ecstasy.

Pohlman faces two counts of attempted first-degree rape, four counts of forcing ingestion of controlled substances, four counts of third-degree assault, four counts of recklessly endangering another, four counts of harassment, two counts of first-degree rape, two counts of first-degree kidnapping, and three counts of first-degree sexual abuse.

Pohlman, a computer technology specialist, was arrested shortly after midnight Wednesday at the Portland airport as he returned from a trip to Thailand.

At his arraignment in Multnomah County Circuit Court Thursday afternoon , a judge ordered him to have no contact - directly or indirectly - with any of the four victims police identified.

Pohlman nodded his head in agreement.

During a search of the house he rented at 7114 N. Chase Ave., which he shared with his ex-wife, police located 24 tablets of suspected ecstasy from a safe in his bedroom. They also found two tanks of nitrous oxide, and an autoinjector at his home.

Pohlman is still being held on $2 million bail. His next court appearance is March 22 at 9:30 a.m.
